Casimir Mozolf w zw ATTORNEYS United States Patent 3,463,141 MALECONTRACEPTIVE Casimir Mozolf, 356 N. Ogden St., Buffalo, N.Y. 14206Filed May 15, 1967, Ser. No. 638,395 Int. Cl. A61f /37, 5/42, 5/44,5/48; A61b 19/00 US. Cl. 128--1 2 Claims ABSTRACT OF THE DISCLOSURE Thecontraceptive is a soft, resilient, moisture impervious, elongated pluginsertable endwise, when moistened, into the orifice of the urethrawithout discomfort and having suflicient area of contact, and preferablya series of endless external transverse ribs, to prevent ejection inresponse to fluid pressure in the urethra. Desirably the body is ahollow rubber body containing a distending spring and a head is providedto limit insertion of the body as well as to facilitate manual removal.The device can also be used, in the event of incontinence, to preventescape of urine.

The present invention relates to a male contraceptive arranged to plugthe urethra at the discharge orifice thereof. Objects of the inventionare to provide such a male contraceptive which is easy manually toinsert and remove without discomfort and requiring no specialapplicator, which can be worn with comfort, and which is effectivelyretained when worn to prevent the discharge of fluid which may tend toeject it.

In the drawings, FIG. 1 is a side elevational view of the contraceptive.FIG. 2 is a top plan view thereof. FIGS. 3-5 are sections taken on thecorrespondingly numbered lines of FIGS. 1 and 2.

The contraceptive comprises an elongated hollow flexible rubber bodyforming a chamber 11 having a rounding head 12 at its inner end andhaving side walls 13 which are shaped so that the body is ofprogressively enlarging cross sectional size toward the outer end 14 ofthe body. This outer end 14 is formed to provide a reduced neck 15 andpart of an enlarged head '16, the chamber 11 having an open end 18 inthis head. A series of endless external ribs transversely encircle thebody 13, these comprising a smallest diameter rib 19 near the end head12, a largest diameter rib 20 near the center of the body, and asmallest diameter rib 21 near the neck 15.

A feature of the invention is that the external transverse dimension ofthe body in a vertical direction (FIG. 1) is greater than its externaltransverse dimension in a horizontal direction (FIG. 2) and that thebody is soft and resilient. This resilience is provided by an internalwire spring 25 having a coil 26 nested in the end head 12 andloop-shaped arms 28 which form continuations of the ends of the coil 26and extend lengthwise of the body 10 and press outwardly against itsside walls 13 so as to distend the rubber body 10 laterally in alldirections. The neck 15 is kept from distending by a rubber band 29, andthe head 16 is completed by a flexible end disk 30 which can beadhesively secured to the end face 31 of the head 16 so as to cover itsopen end 18.

In use, the body 10 is moistened as by saliva, and its head 12 insertedinto the orifice of the urethra with its "ice long or vertical dimensionupright, thereby to conform to the cross sectional shape of the urethra.The body 13 is then fully inserted by end pressure against the head 16,30, the walls of the urethra serving to contrast the transverse size ofthe body 13. When fully inserted, the head 16 is against the orifice ofthe urethra and the expansive pressure of the spring 25 insuresretention of the body in the urethra. The body 13 has sufficientexternal area in contact with the walls of the urethra to insure againstejection in response to fluid pressures in the urethra and prevention ofsuch ejection is further insured by the ribs 19, 20 and 21.

The device can easily be removed from the urethra by pinching the maleorgan behind the small end of the device and thereafter pushing to forceout the device.

I claim:

1. A male contraceptive, comprising an elongated, manually soft,hollowflexible walled rubber body having a continuous moistureimpervious wall at its inner end and extending to adjacent its outerend, the transverse external dimension of said body in one directionbeing substantially greater than its transverse external dimensionperpendicularly to said one direction, a spring wire coil arrangedwithin said body and having arms forming continuations of the ends ofsaid coil and extending lengthwise of and in contact with oppositeinterior sides of the flexible walls of said body and exerting anexpansive force against said walls, a head at said outer end, a neckintermediate said head and body and integral therewith, and a bandencircling said neck to prevent substantial expansion thereof, said bodybeing compressible by the walls of the urethra to being insertable, whenmoistened and with its said inner end leading, into the orifice-of theurethra without discomfort, with the greater transverse externaldimension of said body generally aligned with the greater transversedimension of the urethra, said head being of larger size than saidorifice to limit such insertion of said body into the urethra and tofacilitate its manual removal therefrom, and said elongated body havingsufficient area of contact with the walls of the urethra to resistejection in response to fluid pressure in the urethra.

2. A male contraceptive as set forth in claim 1 wherein said body has aseries of integral endless ribs transversely encircling said body.
